Hello,
I am relatively new to the shotgun community, but I have an important question about the first gun that I bought.
The Parkemy 410 3" double barrel poacher's shotgun was the gun in question, and when I bought it the dealer said that although it had 3" chambers I can only shoot 2" 1/2 cartridges through it. I couldn't really get a straight answer as to why that was, only that it wasn't proofed for 3" cartridges.
The gun has the spanish APM proof mark on it, but could it be that this gun was proofed for black powder cartridges rather that the modern nitro celulose equivalents, or could it be that the gun is fairly old so it's standard practice to shoot lighter loads through it?
If anyone has any knowlegde in this field and can shed some light on it that would be very helpful.
Regards
Jon
